“…Nowadays, molecular‐based QCA cells are being designed with the concept of two‐dot QCA cell and four‐dot [13–18] QCA cell. These concepts are also used to design semiconductor‐based on various materials [19–21]. Establishing digital logic in CBC is an idea that came from a special feature of it, i.e.…”

“…Quantum cellular automaton (QCA) is a computation paradigm achieved by using qubits instead of classical bits for representing states of CA systems [17]. Two-dot [18][19][20][21][22][23] and fourdot models [24] of a QCA cell have been proposed for different types of materials [25][26][27]. Collision of two or more particles is the basis of CBC which can be exploited to realize digital logic.…”

Actin is a biological protein that provides support to the cellular structure and plays a crucial role in cytoskeletal and intra-cellular signalling events. Logic circuits can be designed with actin filaments with the help of actin quantum automata. The authors use a rule (4,27) to implement some novel designs of logic subtractor circuits on this automata to achieve the difference in two binary bits. Logic design of both half and full binary subtractors is proposed in this study. Actin-based quantum cellular automata can be used in different combinations of input to get optimised results from the circuits. The authors focus on consolidating the designs inside single automata block to generate output in a less number of timesteps and less overheads. The designs are simulated with Simulink and this way output is verified for these different design approaches. Reliability and fault-tolerance check is another interesting part of this study. To get a better idea of the optimisation achieved, the authors have also presented a comparative study between the proposed designs in terms of circuit size and efficiency. With all these parameters involved, this study explores opportunities for future implementation of unconventional computing in nano-scale and cost-effective bio-molecular networks.

Quantum-dot cellular automata (QCA) is a field-coupled nanotechnology with unique computing paradigms to be one of the strong alternatives to replace the traditional complementary metal oxide semiconductor (CMOS) in the future in theory. With the development of its fabrication technique and increasing circuit scale, the modular design method of QCA circuits is promoted, which consists at least of two connotations: designing appropriate modules for circuits and allocating applicable clock to circuits. In this paper, a module-based design method using a clocking scheme (MCS) in QCA is proposed, which can be categorized into the modular design methodology. A complete module
